40 Years of Solving Industrial Wastewater Challenges
A family-run engineering company from Sint-Oedenrode, Netherlands — supplying custom wastewater treatment systems to industrial clients worldwide since 1982.
Engineering water treatment solutions since 1982
VDZ Aqua B.V. has its roots in more than four decades of industrial wastewater engineering. The company was founded by Jan van Sinderen and has grown through the experience of several specialist organisations — including Pielkenrood and Nijhuis — building a knowledge base that is rarely matched in the industry.
Today, VDZ Aqua operates from Sint-Oedenrode in the Netherlands, designing, engineering and supplying complete wastewater treatment systems for industrial clients in sectors ranging from food & beverage and meat processing to chemical manufacturing and municipal water treatment.
What sets VDZ Aqua apart is our refusal to offer off-the-shelf solutions. Every project begins with a thorough analysis of the client's wastewater composition, flow rate, discharge requirements, and space constraints — resulting in a system that is engineered exactly to specification.
